Ruiz shot Hinojos multiple times after the two got into a physical altercation in a neighborhood near the University of Texas at San Antonio, Detective Ricky Lopez testified Friday in the 289th District Court, which specializes in juvenile cases.

The hearing continued Monday but Judge Carmen Kelsey had not yet issued a ruling by the end of the day.

Ruiz then stole Hinojos' Toyota Camry and left the presumed murder weapon — a .38 caliber revolver — at the house of a friend's stepmother, Lopez said. The stepmother discovered the handgun later and immediately called police, he said.

In addition to the capital murder charge, Ruiz is charged with two counts of robbery. He also faces charges of harassing a public servant, assaulting a public servant, evading arrest and aggravated assault with a deadly weapon.
